This has been happening to me the last 4 months and even with Studio. I cannot launch the Roblox player by pressing play on the website. I get asked to reinstall, which opens it once. When I close it and try to open again via website or the shortcut, nothing happens. With studio I also cannot open places in the asset manager. I have to do it from the website.
I’ve tried uninstalling and reinstalling Roblox numerous times, disabling malware protection and VPN’s and hard deleting all Roblox folders from all directories. The issue persists and it’s making testing my games very annoying.
